摘　　要：基于高德地图API获取到的97953条有效兴趣点数据,以郑州市主城区为研究区,运用OD成本矩阵、反距离权重法和核密度分析法相结合,分析郑州市主城区八类设施的空间可达性及其空间格局。并从2021年7·20郑州特大暴雨的角度进行进一步分析。结果表明:(1)从设施空间分布上看,便民服务设施覆盖面最广,分布相对均衡,休闲娱乐设施覆盖面最小,分布最不均衡;惠济区内各类服务设施密度值最小,设施配置状况较差,金水区内各类服务设施密度值最大,设施配置状况较完善。(2)从应急避难场所服务面积看,整体服务覆盖率过低,覆盖区域主要集中在中原区与二七区,其次为金水区,管城回族区仅有一处应急避难所供居民使用,惠济区尚未建设应急避难场所。(3)从生活便利度水平看,三环内生活便利度水平适中,主要集中在京广铁路沿线区域,三环外生活便利度则较差,主要由一级水平区域所覆盖。Based on the data of 97953 valid interest points of the application programming interface(API)of Amap,taking the main urban area of Zhengzhou as the study area,the spatial accessibility and spatial pattern of eight types of facilities in the main urban area of Zhengzhou were analyzed by using OD cost matrix,inverse distance weighted and kernel density estimation.Further analysis is carried out from the perspective of heavy rainfall in Zhengzhou on July 20,2021.The results show that:(1)From the perspective of spatial distribution of facilities,convenience service facilities have the widest coverage and relatively balanced distribution,while leisure and entertainment facilities have the smallest coverage and the most unbalanced distribution;the density of all kinds of service facilities in Huiji District is the smallest and the configuration of facilities is poor compared with other regions,while the density of all kinds of service facilities in Jinshui District is the largest and the configuration of facilities is relatively perfect.(2)From the perspective of the service area of emergency shelter,the overall service coverage is too low,which is mainly concentrated in Zhongyuan District and Erqi District,followed by Jinshui District.Guancheng Hui District has only one emergency shelter for residents,and Huiji District has not yet built an emergency shelter.(3)From the perspective of the level of life convenience,the level of life convenience within the Third Ring Road is moderate,mainly concentrated in the areas along the Beijing-Guangzhou Railway,while the level of life convenience outside the Third Ring Road is poor,mainly covered by the first level area.
